In consideration of the different resource demands between new and established players, the team has adjusted the purchasing power of the Buy Resources system so as to offer players the best buy.

Let’s check it out.

Originally, the purchasing power was 1 Cent = 4,000 Food, 4,000 Lumber, 2,000 Stone or 1,600 Iron. Now, the newly adjusted system allows players to purchase more resources however still spending the same amount of game cents as before. Now, the new adjusted system takes in consideration the level of your town hall and resource fields, which means now you’ll be able to gain up to 15 times the amount of resources on the original purchase. Your city running out of resources? Get these great buys by a simple few clicks.
So what this means, in effect, is that its encouraging players to buy resources with coins to supplement barb farming to hold EVEN MORE massive armies. Which they will then have to continue to buy coins worth of resources to support, leading to a never ending cycle.

Shrewd.
